i would offer a single Activation-Key for a member with this board. The only obligation would be to follow the guide exactly as stated. please feel free to read the reviews, they are worth reading: Highend-AudioPC.com | Reviews you can click on every single one of them to read the original posting on the internet.

That's certainly a very fair offer. Reviews, otoh, are only meaningful within the context of a particular usb-dac. Most commercial solutions have not been designed with particular attention towards clock integrity or isolation and as a consequence are extremely sensitive to software and hardware induced jitter.

This is certainly an interesting topic, only this thread is about something else entirely
Maybe a new thread would be a more appropriate venue for this discussion.

Till now I've bought two Joro boards to be used at home and during work traveling.

At the beginning I've been very happy to ear my preferred classical music via this xmos implementation.
Then I've tried the Audiophile Optimizer and I can assure I was schocked by new sound, liquid and distortion free.

Now you think there's little to be gained from Os optimizing but, believe me, reality is different. Me too thought the same prior to use win 2012 and Optimizer.
It's as a whole different world!

I hope you can try by yourselves.

Frank

p.s. All these thought are IMHO!

Per example I fail to hear any difference at all by adjusting the latency of the driver. Previously this would be a very critical setting... It is interesting if the annoyance of running server software would still be worth it with this board.

Thanks for the advice. Could you please tell me if there was a difference between Win7 and Win 2012 without AudioPhiler Optimize?

I looked at your page. What you made sounds very interesting. I can test it and organize a hearing with Bulgarian audio fans, but I think that it will be better someone who is not bound to this device to test the Audiophile Optimizer.

Protocol for PCM63 and DAC-s compatible with it (20-bit), also protocol for PCM61 and DAC-s compatible with it (18-bit) have been successfully tested. The aim was to verify the protocols, so it wasn't used reconstruction filter, as an I/V integrated operational amplifier was used. Fs frequencies tested: 44.1kHz to 384kHz.

Pictures are for PCM63 and PCM61. For better seeing the data, oscillograms are made in persistence mode of 50 sweeps.

Yes, ther's a lot of clarity and liquidity to be gained form Win 2012 Server and Audiophile Optimizer.
I had Win7 installed in my pc but now I don't use it anymore.
I know that you have to pay for a new OS and Philip Optimizer Sw BUT, for me, it's worth the extra cost. It's incredible!

Sorry,
I misundertood your answer! It's not so easy to be still smart after a day at work :-))

Anyway going from Win7 to Win 2012 Server you can appreciate a better sound overall.
I only want to underline that the real gain was obtained with the Optimizer Sw. You can't believe how much audio data is affected by the Os.

In the meanwhile, waiting to try your Ak4396 dac, I'd like to say thank you for your kind support about Xmos module.
It's a pleasure to deal with you and your product is a real winner.

What sucks about computer audio and USB in particular is all the noise, just measure an FFT of any USB dac and look at the spike at 10k hz, the computer OS isn't the issue its isolating the ground and power supply. Thinning down the OS and MB usage is just not going after root cause.
